Protect air current ore dressing device of big scale graphite

The utility model discloses a protect air current ore dressing device of big scale graphite, increase the draught fan on current beneficiation system's basis, the aspirator, whirlwind material discharge device etc, this beneficiation system can isolate big scale graphite under the dry state from broken powdered ore, ball -milling technology link does not get into, directly it carries out the flotation to get into the flotation cell, thereby a large amount of big scale graphite material has been protected, make the output of big scale graphite double abovely, the output rate of big scale graphite has been improved by a wide margin. 本实用新型公开了种保护大鳞片石墨的气流选矿装置，在现有选矿系统的基础上增加引风机、抽风罩、旋风落料器等，该选矿系统能够将大鳞片石墨在干态下从破碎的矿粉中分离出来，不进入球磨工艺环节，直接进入浮选槽进行浮选，从而保护了大量的大鳞片石墨原料，使得大鳞片石墨的产量增加倍以上，大幅提高了大鳞片石墨的产出率。
